Consider the equilibrium system described by the chemical reaction below. Calculate the value of Qc for the initial set reaction conditions in a 1.50 L container: 0.00623 mol H₂, 0.00414 mol I₂, 0.0244 mol HI.

Answer : The value of is, 0.00431

Explanation :

Reaction quotient (Qc) : It is defined as the measurement of the relative amounts of products and reactants present during a reaction at a particular time.

The given balanced chemical reaction is,

The expression for reaction quotient will be :

In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted.

First we have to calculate the concentration of

Now put all the given values in this expression, we get

Therefore, the value of is, 0.00431

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
